Steel cut oats in the slow cooker?

So I have the Alton Brown recipe, and a lovely recipe in one of my slow cooker cookbooks. (4:1 water:oats, if you're curious).

But the question for me is can I make half of a recipe in my small slowcooker? A quarter?

You see, I'm aware that I can reheat the oatmeal in the microwave, but therein lies the problem. I don't own a microwave. I only eat one serving of oatmeal in a morning. The recipe makes four servings.

My slowcooker does have a low setting, but I've been doing some reading. While people have cut down the recipe or made it in a slowcooker, they haven't done both (that I've found).

I'm worried about it burning, mostly. If I absolutely need to, I will wait until the weekend to experiment. I'll start it first thing in the morning and eat it for dinner. But if the consensus is the oatmeal will be all right, I will trust you, Serious Eaters.
